Identify the dna change shown in the diagram and explain how that change can result in the increased genetic diversity often seen among siblings. a) the diagram shows crossing over. crossing over increases the genetic variation of the gametes produced in meiosis, by allowing for different allele combinations than present in the parents. this results in greater diversity in the offspring produced. b) the diagram shows a chromosome mutation called translocation. translocation introduces new traits into the gene pool of the gamete by trading genes between nonhomologous chromosomes. this results in greater diversity in the offspring produced. c) the diagram shows crossing over. crossing over introduces new traits into the gene pool of the gamete by trading genes between homologous chromosomes. this results in the formation of more diverse gametes. d) the diagram shows a chromosome mutation called inversion. in inversion, a segment of a chromosome is reversed end to end. inversion rearranges the genes on a chromosome, providing more diverse gametes.

98 points you will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. before you conduct your experiment, you need to form a hypothesis. a hypothesis is a prediction of what you think will happen in the experiment. the hypothesis is a statement that describes “if” a certain set of circumstances are present “then” there will be a specific result that will occur. record your hypothesis here: record the results from step one of the experiment (dropping the objects in the air): first trial: second trial: third trial: record the results from step two of the experiment (dropping the objects in a vacuum): first trial: second trial: third trial: did the experiment support your hypothesis? using the data from your experiment, describe why you believe your hypothesis was either proven or disproven. what forces were acting on the objects dropped in the air? what force was acting on the objects dropped in the vacuum? part two: comparing forces choose two forces and compare and contrast these forces. you must provide two ways that they are alike and two ways that they are different. you may make a list, write in paragraph form, or make a chart. choose two forces and compare and contrast these forces. these must be different forces than used in the prior question. provide two ways that they are similar and two ways that they are different. you may make a list, write it out, or make a chart.
